Yes and IC's velocities also showed some swings.

This was the shocker of today's shooting. Really stout and probably a little tough on the hands if doing a long session. Almost a tie between these and Buffalo Bore for strongest 180's ever recorded.

EAA Limited Pro 4.75" 1354, 1359, 1334, 1344, 1347. Average 1347.6 FPS/ 726 LBS
EAA Super Match 6" 1388, 1404, 1385. 1398, 1391. Average 1393.2 FPS/ 776 LBS

The 10.0 grain charge is up at SwampFox's loadings. Being these are shorter FMJ bullets it was probably OK, but would be higher pressures with JHP's. 
Hence the WARNINGS for FULLY SUPPORTED CHAMBERS that were on SwampFox ammo boxes...
